“I want to apologize to my fellow board member for a disrespectful comment that was directed at her during today’s discussion. It was inappropriate. I also want to apologize to all Uber employees who were offended by the remark. I deeply regret it.”

Bonderman also personally apologized to Huffington, a source with knowledge of the situation said.

The TPG spokesman did not respond to a question asking if Bonderman will leave the Uber board of directors. UPDATE: Bonderman has resigned from Uber’s board, Reuters said. Bonderman, in a statement to Reuters, said he did not want his comments to create distraction for Uber, which is working to rid its culture of sexual harassment and discrimination. His resignation from Uber’s board is effective Wednesday morning.

Bonderman, who co-founded TPG in 1992, joined Uber’s board of directors in 2013 after TPG participated in a $258 million funding round in the company, led by Google Ventures.
